Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
The utility model will be further described in the following with reference to specific embodiments thereof,
as shown in fig. 1-4, a side-edge bottom-sealed three-dimensional paper bag comprises a bag body 0 composed of a front surface 1, a side surface 2 and a bottom surface 3, wherein a bag opening 4 is defined at the upper end of the bag body 0 by the front surface 1 and the side surface 2, the front surface 1 is symmetrically formed at two ends of the bottom surface 3, the side surface 2 comprises connecting surfaces 21 formed at two sides of the front surface 1, the connecting surfaces 21 can be turned over relative to the front surface 1, the connecting surfaces 21 at two sides of the front surface 1 at one end are connected to the connecting surfaces 21 at two sides of the front surface 1 at the other end through glue, a bottom edge cover 211 is formed at one end of each connecting surface 21 close to the bottom surface 3, and the side surface is connected with the bottom surface through glue by the bottom edge cover 211. Specifically, in the paper bag, after the front surface 1 is folded and erected relative to the bottom surface 3, the connecting surface 21 is folded relative to the front surface 1, so that the connecting surfaces 21 on the two front surfaces 1 are close to each other and then are bonded and connected through glue, and then the complete side surface 2 is obtained, and finally the bottom edge 211 is bonded and connected to the bottom surface 3 through glue, and finally the formed bag body 0 is obtained. The bag body 0 obtained through the above steps has the advantages that the connecting surface 21 is connected to the bottom surface 3, and the bottom edge 211 can assist the bottom surface 3 in bearing, so that the bearing capacity of the bottom surface 3 is improved.
Further, the bottom edge cover 211 can be folded relative to the connecting surface 21 and connected to the lower end of the bottom surface 3 through glue. Specifically, after the side surface 2 is erected and connected to the bottom surface 3 for forming, the bottom edge 211 is turned over and attached to the lower end of the bottom surface 3 through glue, so that the side surface 2 and the bottom surface 3 are connected, because the bottom edge 211 is connected to the lower end of the bottom surface 3 to wrap the lower end of the bag body 0, a leak at the lower end of the bag body 0 is avoided, and meanwhile, the bottom surface 3 also avoids the bottom edge 211 from contacting with an object in the bag and directly bearing the load, so that the connection between the side surface 2 and the bottom surface 3 is not easily broken.
Further, the bottom wrapping edges 211 are connected in an up-and-down overlapping mode through glue. Specifically, when the bottom covering edge 211 is overlapped up and down, the overlapped parts of the bottom covering edge 211 are connected by glue, and the connection between the side surface 2 and the bottom surface 3 is firmer when the connected bottom covering edge 211 is connected to the bottom surface 3.
Further, the connecting surfaces 21 are sealed and connected in an up-and-down overlapping manner by glue. Specifically, when the connecting surface 21 is overlapped up and down, the overlapped parts are connected by glue, so that a firm side surface is obtained.
As shown in fig. 5 to 8, the inner folding creases 5 are formed on both the side surfaces 2 and the bottom surface 3. Specifically, the packaging bag can be folded through the inner folding pressure marks 5 after being formed, so that the packaging bag is more convenient to store and transport. The folding mode of the packaging bag comprises a pointed bottom mode in which the side surface 2 is folded inwards, the bottom surface 3 is folded inwards and protrudes, and an M bottom mode in which the side surface 2 and the bottom surface 3 are both folded inwards.
As shown in fig. 3-4, the mouth 4 is formed with a crease 6. Specifically, 4 departments of sack accessible turn over 6 book of turn-ups creases to form and have multilayer structure sack 4 increases the intensity of sack 4 makes this packing carton more firm.
As shown in fig. 2, a handle 7 is connected to the bag opening 4. Specifically, hand (hold) 7 is connected to sack 4 to the user carries and takes this wrapping bag, hand (hold) 7 can be the slice, also can be the round handle.
Furthermore, a through hole 8 is formed on the bag opening 4, and a lifting rope is connected to the through hole 8. Specifically, in addition to connecting a handle to the bag opening 4, a lifting rope may be passed through the through hole 8, and the lifting rope may be fixed to the bag opening 4 by attaching an iron buckle, so that a user may carry the bag.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered by the protection scope of the utility model.
